Application filed July 21,

To all whom it may concern:

Be it known that l, NAYNL P. ZENT, a citizen of the United States, residing at 203 Eighth Street, in the city of Troy, county of Rensselaer, and State of New York, have invented a Metal Feeder for 'lypographical lllachines, of which the fol lowing is specification, reference being had therein to the accompanying drawings.

liiy invention relates mainly to typographical machines, such as linotype machines, of the general organization represented in Letters Patent of the United States No. 436,532, to O. Mergenthaler, wherein ingots of metal are placed in a melting pot provided for the service of a flow of molten metal to the casting mechanism of the linotype.

These machines are generally equipped without means other than the dropping of the ingots into the metal pot by the operator or attendant of the machine at such times as required.

l d present invention is intended to overcome the objections and loss of time in maintaining a proper supply of metal to the melting pot by providing a metal feeder having a magazine for the containing of a plurality of ingots of metal and a retaining and releasing mechanism whereby the metal can be supplied to the metal pot by the operator without leaving the keyboard operating position or by mechanical means whereby the ingot releasing mechanism may be actuated by a moving mechanism of the linotype to release an ingot from the plurality of ingots in the magazine when and at the proper time required for a replenishment of the metal supply in the metal pot,

In the accompanying drawings I have shown my invention as applied to a linotype machine, but'it is also adapted for use and may be similarly applied to other forms of typographical machines and all other machines wherein a continuous source of metal supply is necessary for the proper mainteance and continuance of production or work as supplied by such machines.

Generally speaking, I desire that it is to be understood that I do not limit myself to any specific form or embodiment, except in so far as such limitations are specified in the claim.

Referring to the drawings:

Fig. 3 is a horizontal section taken on the broken line 3--3 of Fig. 2.

Fig. 4 isa vertical cross section taken on the broken line a e of Fig. 2.

Fig. 5 is a vertical cross section taken on the broken line 5 5 of Fig. 2.

Referring to the drawings wherein the inventlon is shown in preferred form, 1 is the frame of a linotype machine, 2 is the magazine of my metal feeder, 3 the front bracket supporting feeder, at the back bracket supporting feeder, 5 the fulcrum lever actuating releasing mechanism, 7 pulley'over which cable runs to operating position, 9 the cable attached to fulcrum lever 5 and extending through the pulley 7 to foot pedal or hand lever located in a convenient place for the operator for operation without leaving operators position, 10 the metal ingots, 11 the magazine assembly bottom plates, 12 front bracket swivel stud, 13 releasing mechanism beam, 1 fulcrum lever spring, 15 ingot buffer, 16 linotype metal pot, 17 linotype pot plunger rod, 18 linotype pot plunger rod pin, 19 ingot retaining front pin, 20 ingot retaining backpin, 21 releasing mechanism bearing, 22 stop for retaining back pin, 23 stop for retaining front pin, 2 1 spring for retaining back pin, 25 back bracket magazine slideway, 526 back bracket magazine supporting hanger, 27 back bracket magazine supporting hanger spring. I prefer the application and use of my invention as follows:

The magazine 2 wherein is mounted the a releasing mechanism is attached to the linotype 1 by the supporting brackets 8 and 4-.

The magazine 2 is loaded with a plurality of ingots 10.

The magazine 2 being mounted on the supporting brackets 3 and l in an inclined position the ingots 1O slide downward in the magazine 2 until stopped by the ingot retaining back pin 20.

' hen desired to supply more metal to the linotype metal pct 16 the operator presses a hand or foot lever, not shown, mounted in a convenient place so the operator is not obliged to leave the operating position. To this foot or hand lever is attached one end of the cable 9 which runs over the pulley 7 and the terminating end attached to the fulcrum lever 5, and thus the action of the foot or hand lever is extended likewise to the fulcrum lever 5, which depression of the fulcrum lever 5 and its connection with the releasing mechanism beam 13 raises theback retaining pin 19 and allows an ingot to slide downward until stopped by the front retaining pin 20 which is thrust into the channel of the magazine 2 when the foot or hand lever is released by the operator and the fulcrum lever 5 returns to its normal position by the action of the fulcrum lever spring 142 and the retaining pins are likewise returned to their normal position as shown in the drawings allowing the ingot which was held by the front retaining pin 19 toslide downward into the linotype metal pot 16 and the back retaining pin 20 being now thrust and held in the channel of the magazine 2 by the tension of the fulcrum lever spring 14 the ingots 10 remaining in the magazine 2 are held from downward sliding.

It can be readily seen that with the magazine 2 supplied with a plurality of ingots 10 the operator can maintain a continuous metal supply to the metal pct 16 as and when required by simply pressing a foot or hand lever and without leaving the operatlng position to do so.

As ordinarily equipped the linotype is not supplied with a metal feeder and the operator is required to maintain the proper and continuous supply of ingots to the metal pot by leaving the operating position when indications point to a replenishment of the metal or by a low metal alarm now on the market and which may be applied to the linotype. In either event the operator must leave the operating position and drop an ingot into the linotype metal pot 16 by hand causing an interruption in operation and a consequent loss of time, together with various annoyances well known to the users of linotypes.

My invention overcomes these objectionable features and loss of the operators time by controlling the delivery of a plurality of ingots one at a time to the linotype metal. pot by the operator without lOss of time or a leaving of the operating position.

The molten metal in the linotype metal pot 16 requires a constant and even temperature and the insertion of an ingot without preheating lowers the required temperature and causes many' times a loss of time or interior production by the linotype.

As in my invention the ingots 10 in the magazine 2 are preheated due to the application of my invention above the metal pot 16, the individual ingots are sufficiently preheated by the heat arising from the molten metal in the metal pot 16 comingin contact with the magazine 2 and therefore the ingots 10 in the magazine 2 are preheated before delivery to the metal pct 16.

in my drawings 1 have shown a releasing mechanism operated by the operator of the linotype but this may be accomplished by any known form of automatic or manually actuated mechanism.

In my drawings 1 have shown my invention attached over the cam mechanism of the linotype but it can be placed in an upright, horizontal and various other positions in various locations about the machine but all with a terminus in the metal pot 16.

As shown in my drawings the front bracket 3 is provided with a swivel stud 12 mounted in the sides of the magazine 2 and the back bracket a is provided with a magazine slideway 25, a magazine supporting hanger 26 and a hanger spring 27 all providing so that the magazine 2 and its attached mechanism will raise at the terminus end which may extend into the metal pot 16, this provision being made as the action of the linotype metal pot evolves a tilting,

forward and backward motion and therefore as shown attached in my drawings my invention must provide for all actions of the linotype metal pot 16.

As shown in preferred form in my drawingsthe ingot buffer 15 enters the metal pct 16 and being formed to deflect the ingots 10 from the sides of the metal pot 16 when delivered thereto by the releasing mechanism of my invention. Also acting as a buffer to retard the force of gravity of the ingot 10 so it will slide easily into the metal pct 16 into the proper location therein and without undue splashing of the molten metal in the metal pot 16 or in any way interfering with the proper actions of the metal pot mechanisms and its component parts as located thereon.

I have shown the linotype plunger rod 17 and the linotype plunger rod pin 18 to place the location of the mounting of my invention in the clear of the action'of the linotype plunger and its mechanisms.

I show a back pin retaining spring 24 which allows for a variation in depression of the back retaining pin 20 should an ingot 10 remain thereunder when the fulcrum lever 5 is returned to normal position.

ingot front retaining pin 19 and ingot back retaining pin 20 are both provided with means of adjustment and lock to obtain a certain length to that part of the pins extending below the releasing mechanism beam 13; all providing for the use of varying thicknesses of ingots 10 in the use of my invention.

Ingot front retaining pin 19 is provided with a stop 23 mounted on the releasing mechanism beam 13 to obtain a certain fixed distance of downward travel of the releasing" mechanism beam 13 when the fulcrum lever 5 is in normal position and likewise the ingot back retaining pin 20 is provided with a stop 23 to obtain a certain fixed distance of downward travel of the releasing mechanism beam 13 when the fulcrum lever 5 is depressed.

In preferred form of construction magazine 2 will be of two sections joined by the magazine bottom plates 11.

The releasing beam 13 carries a fixed shaft, 21 mounted crosswise therein and working free at both sides in the suitable bearings; the fulcrum lever 5 being mounted as an integral part of the roller and releasing beam 13 on the outside of one of said bearings.

As previously stated, I have shown my invention only in preferred form and by Way of example, and as applied to the specific kind or machine indicated. Obviously, many modifications and alterations therein, and in its mode of adaptation, will suggest themselves to those skilled in the art, without de parture from its scope.

Having thus described my invention, its construction and mode of operation, what I claim and desire to secure by Letters Patent of the United States, is as follows:

In an ingotfeeding mechanism, the combination with a movable melting-pot; of an ingot-chute rockable upon a horizontal axis arranged to be rocked by movement of the melting-pot while permitting movement of translation of the melting-pot relatively to the chute.
